Does this 2.2 kW motor require a specific voltage setup?

Yes, this model is designed for 380V AC input. It must be paired with a 3-phase Variable Frequency Drive (VFD) that matches this voltage to operate correctly at the required 400 Hz frequency.

What is the benefit of the ER20 collet over ER11 or ER16?

The ER20 collet system is more robust and supports larger tool shanks—up to 13mm. This allows for the use of larger material removal bits and provides higher clamping force, which is essential for the 2.2 kW power rating when performing heavy-duty milling.

How often should I check the water cooling system?

The water cooling system is vital for protecting the P4 grade bearings. We recommend checking coolant levels and flow daily before starting production. For industrial use, using a water chiller with flow alarms is the best way to ensure the long-term reliability of the motor.
